C# APIs are chock-full of generics. Generic types, generic method parameters, generic return types, generic fields, generic properties, deriving from generic types, and generic constructors. We can find all of these in the Unity and .NET APIs. Some are more frequent than others, but we’re going to need support for all of them to make C++ scripting a viable alternative to C#. Today’s article continues the series by adding just that: support for all of these kinds of generics. Let’s dive into how to use them as well as some bonus items added to the project this week.

Last week’s article mostly covered abstract classes, but this week we’ll discuss an even more abstract type of class: static classes. We’ll also explore C#’s anti-constructor, known as a destructor, and some fancy ways to construct a class. Read on and learn some more class-related features that were never available to us in AS3.

It’s very nice in AS3 to simply state the name of a function and get a Function variable back, regardless of whether or not it is a method, static method, dynamic function, or plain function in a package. Most other languages do not allow this level of convenience. Java doesn’t allow it at all and C++ and AS2 require fanciness in order to pass the this pointer. However, when you want a Function for the constructor of a class, you get a Class variable back. This article will show you a way to get a Function variable that will create an instance of a class when called.
